MACHINE FOR MAKING CORDAGE.

SPECIFICATION forming" part of Letters Patent No. 505,632, datedSeptember 26, 1893.

Application filed September 12, 1892. Serial No. 445.588. (No model.)

To a whom it may concern.-

Be it known that I, BERNARD J. MOGEE, a citizen of the United States,and a resident of Cambridge, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Machines forMaking Cordage, of which the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to improvements in machines for making cordageand it has for its object to gear the driving shaft directly to thegrooved revolving disk by which the travelers are rotated, and. therevolving cam disk by which the travelers are moved radially in and out,for the purpose of preventing back lash and causing a true movement tobe imparted to the travelers which being received in and leaving thestationary gear ring, thus producing a positive and uniform motion ofthe travelers relative to the stationary gear ring and overcoming theusual objection common in other machines, namely, the wear and tear ofthe travelers while being taken and delivered by the cam slides.

The invention also has other objects which will hereinafter appear.

The invention consists in the features of construction and thecombination or arrangement of devices hereinafter described and claimed,reference being made to the accom panying drawings, in which- Figure 1represents a plan view of the machine showing parts in section and theupper bearing ring as removed. Fig.2 represents a longitudinal sectionon the line X shown in Fig. 1. Fig. 3 represents a plan View showing aportion of the upper bearing ring, a portion of the stationary gear ringand pinions as removed. Fig. 4. represents a detail side elevation ofone of the travelers. Fig. 5 represents a plan view with the guide coverin position. Fig. 6 represents a detail plan View of the guide cover.Fig. 7 represents a cross section on the line 7-7 Fig. 5, and Fig. 8represents a cross section on the line 88 Fig. 6.

Similar letters refer to similar parts whereever they occur on thedifferent parts of the drawings.

In the drawings A, A, represents the frame D is a bevel gear the hub ofwhich is se cured to the sleeve C as shown in Fig. 2.

E is a circular grooved disk the hub of which is secured to the upperend of the sleeve C, said disk having circular grooves e, e, onits-upper side as shown in Figs. 1, 3, 5, and 6 for guiding thetravelers F (shown in Fig. 4) in a circular path during the cordingoperation. To the central part of the plate E is secured a guide cover 0having a series of guide surfaces 0 which serve as continuations of thegrooves e by which the webs f of the thread carrying travelers F areguided in a circular path during the cordage operation.

G-is a bevel gear forming a part of a circular disk G which is journaledon the hub of the grooved disk E and is provided on its upper side witha cam grdove g that actnates the cam slides H by which the travelers areactuated and moved to and from the stationary gear ring I.

The mechanism for imparting a quick rotary motion to the bevel gear Dand its grooved disk E and a comparatively slower rotary motion in thesame direction to the bevel gear Gand its cam disk G is constructed inthe following direct and simple manner: K is the driving shaft journaledin bearings in the frame A, A, and provided with fast and loose pulleys7c and shown in Figs. 1 and 2.

To said shaft K is secured a pinion K the teeth of which mesh in theteeth of the bevel gear G as shown in Fig. 2. K is another andpreferably larger pinion, secured also to the shaft K, the teeth ofwhich mesh in the teeth of the bevel gear D as shown. By thisarrangement I dispense with an intermediate shaft and gear, and connectthe driving shaft positively and directly by means of pinions to therespective bevel gears D and Gfor the purpose hereinabove set forth.

In practice I prefer to arrange opposite to the driving shaft K, a shaftL located in bearings in the frame A, A, and having secured to it thepinions L and L" meshing in the teeth of the respective bevel gears Gand D as shown in Fig. 2.

To the outer end of the shaft L is secured a bevel pinion l, the teethof which mesh in the teeth of the bevel gear m secured to the verticalshaft M connected to the take up device for taking up the finished cord,such take up device being however not shown in the drawings as it doesnot form any part of my invention.

Each cam slide II has in its outer end, a pin or pin and roll hprojecting into the cam groove g on the disk G by which a radialreciprocating motion is imparted to the cam slides during the rotationof the disks E and G for the purpose of intermittently anchoring thetravelers F in the notchesi on the stationary gear ring I and guidingthem into the grooves e, e, on the disk E during the cording operation.

E, E, are pinions journaled on pins e, e, secured to the rotary disk E,which pinions mesh in the teeth of the stationary gear ring I and servethe purpose of guiding the thread carrying travelers F intermittently incircu lar paths in the grooves c, e, on the disk E as is common inmachines of this kind. Each cam slide II has at its outer upper end,acam groove h adapted to receive a web or projectionfon the lower end ofthe traveler F as shown in Figs. 2, 3 and 4. By the reciprocation of thecam slides the travelers are intermittently moved out of the grooves e,e, and inclosed in the notches i, 2', on the stationary gear ring andguided from thelatter into the grooves e, e, and carried by the pinionsE, E in circular paths to be again temporarily anchored and so on.

fistheshanknearthelowerendofeachtraveler which is anchored in thenotches ion the stationary gear ring I. In practice however I have foundthat such shank and gear ring are not sufficient to properly anchor thetraveler on account of the severe tensional strain exerted on thetraveler by the thread while making the cordage and to overcome suchobjections I secure above the ring I a secondary bearing or anchoringring N, having notches n, n, adapted to receive an upper shank f on thetraveler which shank is separated from the lower shank portion f bymeans of an annular flange f adapted to enter the intervening annularspace between the rings I and N as shown in Fig. 2, by which arrangementthe travelers are firmly held and anchored in position after beingpushed outward by the cam slides and until they are again guided intothe circular grooves e, e.

In the operation of the machine the travelers are intermittently rotatedaround their own axes as well as around the central axis of the machineand anchored as above described by which the cord is formed by thethreads carried on the travelers as is usual in machines of this kind.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. In acordage making machine, the combination with a stationary toothed andnotched gear ring I, of a secondary notched bearing ring N restingdirectly upon the upper side of the toothed and notched gear ring andhaving a flange extending over said ring, the travelers F each providedwith two shanks f f and an intervening annular flange f which latterrests at intervals directly upon the upper surface of the toothed andnotched gear ring and against the under surface of the flange on thebearing ring, and the intermittently reciprocating slides I-I,substantially as and for the purpose described.

2. In a cordage making machine, the combination with a stationarytoothed and notched gear ring I, of a secondary notched bearing ring Nresting directly upon the upper side of the toothed and notched gearring and having a flange extending over said ring, the travelers F eachprovided with two shanks f f and an intervening annular flange f whichlatter rests at intervals directly upon the upper surface of the toothedand notched gear ring and against the under surface of the flange on thebearing ring, a rotary disk G provided in its upper surface with a camgroove 9, and a series of radially movable slides II each provided onits lower side with a stud or roller h engaging the cam groove of therotary disk and in its upper side with a groove h to receive a partofthe travelers, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 6th day of April, A. D.1892.
